Ski DIN Calculator
Look up the recommended DIN release setting for your ski bindings from weight, height, age, skier type and boot sole length, following the ISO 11088 chart method. Use it to understand your setting, then have a certified shop set and test the bindings.

How to use the Ski DIN Calculator
- Enter weight and height in kg/cm or lb/feet and inches.
- Enter the age of the skier.
- Find the boot sole length (BSL) in mm on the boot heel and enter it.
- Choose the skier type that matches how the skier usually skis.
- Read the DIN value and take it to a ski shop to have the bindings set and release-tested.
How the DIN chart works
| Code | Weight (kg) | Weight (lb) | Height |
|---|---|---|---|
| A | 10–13 | 22–29 | |
| B | 14–17 | 30–38 | |
| C | 18–21 | 39–47 | |
| D | 22–25 | 48–56 | |
| E | 26–30 | 57–66 | |
| F | 31–35 | 67–78 | |
| G | 36–41 | 79–91 | |
| H | 42–48 | 92–107 | 148 cm (4'10") or less |
| I | 49–57 | 108–125 | 149–157 cm (4'11"–5'1") |
| J | 58–66 | 126–147 | 158–166 cm (5'2"–5'5") |
| K | 67–78 | 148–174 | 167–178 cm (5'6"–5'10") |
| L | 79–94 | 175–209 | 179–194 cm (5'11"–6'4") |
| M | 95 and up | 210 and up | 195 cm (6'5") and up |
Codes N and O are reached only through skier-type adjustments. Start with the weight code and the height code, take whichever is closer to A, then adjust: Type 2 moves down one row, Type 3 two rows, Type 3+ three rows, Type −1 up one row, and age 50+ or 9 and under up one more row. The final row and the boot sole length column give the DIN.
Important safety notes
- This tool reproduces the widely published chart method for information only. It does not replace a shop setup.
- Binding manufacturers publish their own charts and limits; follow them if they differ.
- Check that your binding's DIN range covers the result and that your boots are compatible (alpine, GripWalk, touring soles).
- Re-check the setting when your weight, skiing style or boots change, and have bindings tested at the start of each season.
Frequently asked questions
What is a DIN setting on ski bindings?
DIN is the release value on a ski binding, set on a scale typically from about 0.75 to 16 or more. A higher number means the binding needs more force to release the boot. The name comes from the German standards body, and the method is now defined in ISO 11088.
How is the DIN setting calculated?
Find a skier code letter from weight and from height and use whichever is closer to the top of the chart. Move down one row for Type 2 or two rows for Type 3 skiers, and up one row if the skier is 50 or older or 9 or younger. Then read the value in the column for the boot sole length.
What skier type am I?
Type 1 skiers ski cautiously at slower speeds on easier slopes and prefer releases on the safe side. Type 2 skiers ski moderately at varied speeds on most terrain. Type 3 skiers ski fast and aggressively on steeper terrain. Type −1 and 3+ are extensions for very cautious or very aggressive skiers.
Where do I find my boot sole length?
Boot sole length (BSL) is the length of the boot sole in millimeters, usually molded or printed on the side of the heel or toe, for example 305 mm. It is not the same as your Mondo boot size.
What happens if my DIN is too high or too low?
Too low and the binding can release during normal skiing, causing a fall. Too high and it may not release in a fall, which raises the risk of leg and knee injuries. That is why bindings should be set and tested by a trained technician.
Can I set my own ski bindings?
You can read the setting and see what the shop should use, but certified technicians also check binding adjustment, forward pressure and release with a calibrated tester. Shops following ISO 11088 procedures provide the safest setup, especially for rental or new equipment.
